COPARTNERSHIP COMPOSED 0F HIMSELF AND LEWIS W. GOODELL, OF BEARDS- TOWN, ILLINOIS.

PIPE-STEM.

To all whom t may concern:

Be it known that I, CHARLES D. HILL, a citizen of the United States, residing at Evansville, in the county of Vander-burg and State of Indiana, have invented a new and useful Pipe-Stem, of which the following is a specification.

It is the object of my invention to provide a pipe or cigar holder with a cheap and elticient means, easily removable and rcplace able, for purifying smoke. In attaining this object, I insert in the pipe stem or cigar holder, a removable cartridge composed of a plurality of longitudinal strips, preferably of bibulous material, some intersecting others transversely to form a plurality ot passages, the strips being suitably notched so that the smoke may pass through these passages in succession. rlhese strips are incased in a suitable covering, also preferably of bibulous material, and are provided with end pieces suitably notched to allow the entry and exit et' the smoke from the cartridge. l

The accompanying drawing illustrates my invention.

Figure l is a vertical longitudinal section through a pipe embodying my invention; Fig. 2 is a perspective View of the cartridge, with the cover and one end piece removed and one of the strips partly broken away; Fig. 3 is a perspective section taken on the central, vertical, longitudinal plane of Fig. 2; Fig. l is a view of the complete cartridge, with one end plate removed; and Figs. 5, (i, and 7 are perspective detail views oit one of the end pieces and one of each of the two kinds of longitudinal pieces forming the cartridge.

The cartridge is composed ot a plurality of longitudinal strips l0 and longitudinal strips 11 arranged at right angles to and intersecting each other, two identical endpieces l2, and a cover or casing 13. These pieces are all preferably formed oi bibulous paper or cardboard. In the arrangement illustrated, there are two each oit the pieces 10 and ll, which are illustrated. in F igs. and 7 respectively. The end pieces 19. of which one is illustrated in Fig. 5, each comprise a dislr having two parallel slots llt spaced from each other and from the edge oitl the disk, and a notch 15 near the end o1 one et' the slots llt but spaced slightly to one side of said slot. Each longitudinal piece is Specification of Letters Patent.

provided with a tenen 1G at each end, ior fitting into one et the slots 111, with two parallel longitudinal slots 17, spacedfrom cach other and extending the full length of the piece 10 except the tenons 1G, and with a notch 18 in and near the end ot one oi its longitudinal edges. Each piece 11 is ot the saine length as the piece 10 minus the tenons oi the latter, and is provided with a notch 1t) in each longitudinal edge and with a hole 20 substantially midway between the two .notches 19, said two notches 19 and the hole 20 all being near the saine end oit the piece.

In assembling the cartridge, the two pieces 10 are turned end lor end and upside down, so that the notches will be near opposite corners, then the two pieces 1l, turned relatively end 'tor end, are inserted through the slots 17 of the two pieces l0, each piece ll passing through a. slot 17 in both pieces 10, then the two end pieces 1Q, turned 180o relatively to each other, are placed at the ends of the strips 10 and 11 so that the tenons 16 pass through the slots 14e, and then the cover or casing 13 is placed around the whole. The cartridge thus formed provides f) passages, a, o, c, cl, c, f, g, 7L, and e', through which, by reason oi the aforesaid notches and holes, smoke may pass in the order named.

The cartridge in its entirety may be mounted in a tube 2l, conveniently ot' metal, which may be a skeleton tube and has projecting end portions beyond the ends ot the cartridge to receive the end 22 ot the stein 23 of the pipe bowl or cigar holder 211, and the end oit' the mouth-phare 2(3.

In operation, the smoke itroln the burning tobacco in the pipe bowl it or et the burning cigar passes along the central aperture oit the stein 253 until it strikes the end-piece l2 otE the cartridge. lit now passes through the notch in such end-piece l2, along the passage a, through a notch 1f), alongl the passage b, through another notch 19, along the passage c, through a notch 1S, along the passage (Z, throi'igh a hole 20, along the passage c, through the other hole Q0, along the passage f', through the other notch 1S, along the passage g, through a third notch 1t), along the passage t, through the itourth and last notch 1t), along the passage v', and through the notch 15 in the other end-piece l2 to the central aperture in the mouthpiece 2G. In its tortuous passage through the cartridge, the smoke is purified by the removal, by the bibulous material of the cartridge, of the nicotin and other deleterious substances. When the cartridge has absorbed so much nicotin that it begins to act less efiiciently as an absorbent, the mouthpiece 26 and bowl 2% and the stem 23 may be removed from the tube 21, and a new cartridge substituted in such tube for the used one. @n account of the cheapness of these cartridges, such a substitution may be made very frequently.
